A Robot Arm Based Probe Station for Near Field Measurement

Electromagnetic compatibility, or EMC, refers to a product’s or equipment’s ability to operate in its intended environment without producing undue interference or being adversely affected by it. There are two types of measurements which are near field and far field measurements. Both are located around the region of electromagnetic field around the equipment under test (EUT). In this work, an investigation was done for near field measurement. To measure in the near field region, a 3-axis probe station needed to be developed. This probe station consists of a robot arm that can move in 3-axis directions and a probe to measure near field. AR tags are used to represent the measurement points in the simulation. The movement and trajectory of the robot arm was simulated and the attached camera has successfully scan all AprilTags. Results of the simulation shows that the robot arm could be used as the probe station for the measurement in the near field.
